BACKGROUND: Ventriculoatrial shunt (VA) insertion is one of the possible surgical procedures to treat hydrocephalus. However, it is also associated with several complications such as obstruction and shunt infection as well as life-threatening complications like intraatrial thrombus or thrombosis on the distal catheter. In this case report, we share a rare case of a patient with a VA shunt, who was admitted to our hospital with a stroke. CASE DESCRIPTION: A 56-year-old female patient with suspected acute stroke was admitted to the stroke unit. CT and MRI scans showed multiple cerebral infarctions in both hemispheres. The transesophageal echocardiography (TEE) showed at the tip of the VA shunt catheter, which was implanted about 30 years ago due to aqueduct stenosis, also a thrombotic formation as the reason of stroke. Interestingly, the tip of the catheter was not in the right atrium as expected, but in the left atrium. Further evaluation showed a patent foramen ovale (PFO), through which the catheter migrated from the right to the left side. At first, conservative treatment with anticoagulation was started with the aim to dissolve the thrombotic formation; however, a control TEE showed an unchanged mass at the catheter tip. Therefore, a ventriculoperitoneal shunt was implanted and the proximal shunt catheter was removed with an additional closure of the PFO by our heart surgeons. Postoperatively, the patient was discharged 10 days later in good condition to a rehabilitation center. CONCLUSIONS: Thromboembolic events due to a PFO are rare but possible life-threatening complication after VA shunt insertion. Therefore, preoperative cardiac diagnostic might be clinically relevant prior to a VA shunt implantation to avoid such complications.
